If you want to know your chronological age, simply count the candles on your next birthday cake. Calculating your biological age, though, is a little more complicated. Chronological age is the number ...

As anticipation builds for the longer days that follow this weekend’s switch to daylight savings time, the moment seemed ideal to turn to one of the nation’s leading circadian-rhythms researchers, UC ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

Clocks coming out of a large clock as a 3D illustration. We age along two clocks: a chronological clock and a biological clock. The former is just a measure of how many birthdays you have celebrated — ...

When used correctly, they can help us unpick some of the mysteries of our biology, and our mortality. Be honest: Have you ever looked up someone from your childhood on social media with the sole ...

It's Memorial Day, Short Wavers. This holiday, we bring you a meditation on time ... and clocks. There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend ...

A new study shows that the timing of the different clocks in our body depends on multiple stimuli. This was investigated in the liver- and muscle clock of rats, where only a combination of eating and ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks work, ...

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...
